Application letLDecember 27, 1912. Serial No. 738,882.

To all whom t 171,113/ concern lle 1t known that ue, Fur-:neuron Riconns and Mxnnon Lewin', both citizens of the United States, and residents ot' the city ot New York, borough oi" Brooklyn, in the county of Kings and State ot' New York, have invented a new and irnlirovcd ltllectric Fire-Alarm. of which the followingr is a full, clear, and exact description.

Our invention relates to electric tire alarms which may be installed in a building with an indicator on each floor having` a bell and a switch, with electrical connections for ringing all the bells and for lighting a certain lamp on each floor when an alarm is given, by closing one o1' the switches.

Still other objects of the invention will appear in the following` complete specifica tion, in which 'the preferred torni of our invention is disclosed. i

In the drawing, similar characters of reference refer to corresponding,r parts in all the figures.

Figure .l is a perspective view of one of thc indicator boxes with the door open; Fig. 2 is a front elevation of an indicator box; Fig. 3 is a sectional side elevation oi an indicator box shown in Fig. 2; and Fig. 4 is a diagrammatic view showing the wiring.

By referring to the drawings, it will be seen that each of the indicato-r boxes has a rear member 5 with side members G, a top 7, a bottom 8, the front indicator box being normally closed by a door 9 mounted on the hinges 10.` In this indicator box there is a horizontal partition 1 t which, with the top of the box 7, forms a compartment 12, there being another horizontal partition 13 which with the bottom 8 f the box foi-Ins a compartment 111. These artitions 11 and 13 are connected'by av Ver ical partition 15 which forms the rear of thel lamp compartments 16. These lamp compartments are divided by horizontal'melnbers 17.and by vertical members 18, so that one of the compartments 16 will be disposed at the rear of each 'igure or letter, forming lndieating means 19 on the door 9.V These indicating means 19 are constructed by cutting openings 2() in the door in the form of tigures 21 and letters 22, which'in'dicate certain portions of lthe building. These openings 2O are covered at the inner side of thefdoor- 9 by glass 23er some other translucent memf ber. As shown in the drawinii's" there are three vertical columns of thesel compartments '1S each being the rcar ot' one of the italic-ating iucans 1S) consisting` o'l a ligure 521 and a letter 22. `This construction is provided for a four story building, the top row et indicating?r means 19 referring to the fourth tloo1',and the lel't hand indicating means -'l' reterritreto the west end of' the fourth floor, the indicatingr means Ll indif eating: the central portion of the fourth door, and te indicating the east portion of the fourth floor. In the same way the other indict'itini;r means 1S) rel'er to the different tltiors and proportions thcreot, as for instance, the bottom row of the indicating' means referring to the tirst floor, the lelt. hand one 'lv referring to thc west portion ot thev first floor, and l.c indicating),- thc central portion ot the first floor and the ri 'nt hund one l indicating thc east portion ot the first floor.

In the compartment let, at the bottom of each ot' the indicating boxes, there are three switches Q4, each ol'v the indicatiner boxes be-` ing' provided with an electric bell. Each building provided with one of these indieating` boxes on each floor so that when on alarm is sounded, a bell will be rung on each loor and a lamp willbe lighted indicating lwhere the fire is. .The wiring is s own in Fig. 4 of the drawings, in which wires 26 and 27 are the main wires ol." an electric circuit, and the wires Q8 and 2Q are the wires ot the bell circuits, which are connected elec trically with the bells 25 and 25".

-In Fig. 4 of the drawing, we have shown the connections for a two story building, butit will be understood that this saine wiring arrangement may be used in a building of any size and number of stories. The lower indicator box.. in the arrangement shown in Fig. f1 of the drawings has the electric bell 251 and the lamps BO--BLMBQH 33-34 and 35, also 'the switches 3(1--37 and 38. The indicator box in the second stor)T is provided with the lamps 3tlv40--ll-- 42-43 and 44, and with the switches 45 4G and 47; The bell wires QS and "29 are connected with the bell 25" by means of the wires 4S and Lit), and the bell wires 52H and QS) are connected with the bell Q5 by the hell wires 50 and 5l. 'lhc switch 58 is counected with the bell wire 2S b v means of the wires. 52 and 53. The switrlri' is conlun CII

tgbcted with the said bell wire 28 by means of the wires i and 55 and the switch 3G is connected with the bell wire28 by means of the Wires 56 and The bell Wire 29 is connected with the mitin wire 27 by means of the wircs and '59. The switch 47 is connected with the bell wire 28 by means of the wire 6() and (il. .The switch 4G is connected with the bell wire 28 by means of the wires 62' and 63. The switch 45 is conf nected with the bell wire 28 by means of the wires 64 and 65. The switch 38 is connected with the main wire 26 by means of a wire 6G. The switch 37 is connected with the main wire 26 by means of a Wire 67. The `Switch 36 is connected with the main wire 26 by means of a wire 68. The switch 4:7v :is connected with the main Wire'26 by means of a wire 89. The switch 46 is connected with the main wire 26 by means of a wire 70. The switch t5 is connected with theA main Wire 26 by means of a wire7l, The main wire 27 is connected with one set of terminals of the lamps 30-33233-34 and by means, of a wire 72. The main wire 27 is connected with one set of terminals of the lamps-39-4l-fl0-ai2--li3and 44 by I,means of a wirel 73. .The switch 38 is connected with the ,other` terminals oi the lamps 30 and 39 by means of the Wire 52 and the wire 74.- The switch 37 is connected with the other terminals offti e lamps 31 and 40 by means of the Wires 54 and 75. The' switch 36 is connected with the 4other terminals 'of the lamps 32 anddi by means oi 'the Wire 56 and the wireftl, tl'ie switch 47 is connected with the other terminals of the lamps 4s. and '35',by means of the wires and 77. The Switchs@ is connected with the otherterminals of the lai/nps i3. and 3i by -means of the :wires 62 and 78.. The switch 45 is connected with the other ten minals of the lamps 4:2 and 33 by means of the wires 64 and '79.A lit will therefore be seen that "when the wiring which is shown in Fig. 4t is used in a twostory budding, and the indicator with the switches 6-37 and 38 is disposed on the'rst door; and the 'indi- Gator with. theswitehesf-fdti 4and a7 is disposed on they second'ioorgtliatsvhen the switch 38 is closed which refers to the east portion of the rst door, it will connect-,the -main wires 2G and 27 with the bells 25h and.,

by means of the wires 66-52--53-2S- 48-49-29 and 58, and also by means of the wires 50 and 51. Thiswiil ring the bells 25 :and 25, one of which' is located on the first iioor and the other is located lon the second floor. This will sonnd tlielalarm, and the persons 1n the building by looking at Athe indicators not only can tell on which tioor the alarm was given, but also can teli whether the tire is at the central portion of the said floor and at which end saidl floor. ln the diagram sbfm'n in Fig. of!

the drawings, the switch 38 which is on the first floor, refers to the .eastern portion oftthe rstoon and when the switch is closed, it indicates that the tire is at the eastern portion of the first floor. lfVith the closing of the switch, the main Wires 26 and 27 are connected electrically with, thelamps() and 39 by means of the Wires 72 and 73 which, will light the lampe l'and l' 39 as has been stated. Should the. ya-,larrnl bei' given 0n the second iioorjald ,the ,linebein," the central portion of the seconder, the@ switch 46 will be closed which will ringtthe bells 25" and 25a in the mannemintimated,'.V, 7 and Willialso light the lamps 43 and' the circuit extending between the mainwires 26 and 27 by the wires 7 0-62-78f-7l and 72. ln this way not only is anv alarm sound'- ecl, but information vis furnished to allthel persons on every iioor of the buildings() that they may know Where the re is and partment, a second partition forming with the opposite wall ofthe hex a second compartment, a third partition extending substantially from the iirst to the second partition,
